[AG-TECH] Hi-quality video

[Brian Chee]

We've been able to source 22.5mb/sec HDTV (compressed) video feeds from UH
Manoa (island of Oahu in Hawaii) to Moffett Field (NASA Ames).  We used the
2netFX product and it looks promising for stuff like medical imaging and
perhaps later stuff like "Caves" or Flatland type 3d imaging systems.  At
this moment all our work has been in the demonstration mode pulling video on
demand, since HDTV cameras are sooo expensive.

Oh yeah...this has been via unicast and multicast.....
